hm...... i just brought my Oscon T-muso today morning, and its a sure thing to try out
(THIS IS A REVIEW)well.... my audio system in my house aren't that excellent, it just average EACAN E-510A. I'm not an audiophile, and a beginner into audio, but nevertheless i appreciate audio, thus finding the best for my own.
So my testing was doing difference between MP3 and FLAC (lossy and lossless format), and filesize (320,192,96,48 kbps).

hey what the hell with that, i thought was testing T-muso ? "", wait and you will understand.
So the song of selection is 'Listen' from Beyonce. The MP3 are direct convert from the FLAC i have, into several size.
First try was using my netbook soundcard (streamyx free), then use T-muso.

now this is testing !
The procedure is to put all into a playlist then shuffle playlist, then no peeking. After listen to each of them, write my rating for them. After all listened, compare with the list's bitrate (quality). So now.... the result
QUOTE
Netbook soundcard :
Almost all are rated correctly, except for 320kbps and FLAC, which i kinda mixed them both (sound very similar, similar rating).
T-MUSO DAC:
the first time i play it during the testing, it amazed me with the
sound quality it increase !

(sad to say, when i play the DAC before the testing, i couldn't detect the difference. But with testing, i already familiar the sound quality of that song, so it is VERY obvious)
So continue with the result. The overall sound quality floor increase (in almost every different filesize in testing), and the first time with T-muso experiment, The rating of 3 files are similar rating and not correct ! (320kbps, 192kbps and FLAC)
Maybe my ear wasn't that sensitive (since i'm a beginner) So i decided to try it AGAIN (only with T-muso)
This time i get it all right but was difficult to differentiate !

By the way, 48kbps and 96kbps are so easily notice..... super obvious
Conclusion :

for T-muso !

to slevin (if not for you, i can't enjoy more out of music) ! The quality is almost beyond my ear capability to differentiate. But it is better (
ALOT) than i expect (when i met him, first listen to T-muso with his nice headphone, nothing such as hesitation to buy

)
Going to post more result from my experiment, such as using better AMP and Speaker, which is not around me now. also not tested thing like bypassing window audio processing kernel and etc. All going to be in next result
So i will be enjoying "IT" now
